(Since my original release-thread slowly turned into a free-for-all support thread, I’ll communicate new features in separate threads like this one)
I just added a new feature to the latest beta version of ScriptPlayer: Subtitles
For now only external files work, not the ones included in containers (e.g. mkv, but you can extract those).
There are no settings or formatting options, just plain text for now. Should work with ass, ssa (v4) and srt files.
